Carbon Fertilizers for reduced GHG emissions and improved food security


Principal Investigator

End date: 31.12.2019


Summary



This
project investigates the application of nutrient-loaded biochar in less fertile
agricultural soils of Pakistan with additional mechanistic investigations
carried out in Germany. A set of field (Pakistan) and laboratory experiments
(Germany) will be conducted to evaluate the effect of biochar on nutrient use
efficiency and GHG emission per unit of agronomic yield production or per unit
of agricultural land use. The field experiments will be conducted at University
of Agriculture Multan (MNSUAM), Pakistan. All GHG samples collected from the
Pakistan field study will be analysed at Hochschule Geisenheim University
(HGU), Germany where the necessary gas chromatographic methods are established.
The PI in Pakistan (Dr. Haider and his PhD and later master student) will visit
Germany in 2018 and 2019 to learn GHG data analysis with the gas chromatograph
(GC) and subsequent calculations and protocols using R protocols. They will
also conduct controlled experiments (2nd year) using e.g. Pakistan soil or Pakistan vegetable species.



Recently,
the combination of conservation farming methods with using biochar as a carrier
for organic and mineral fertilizers applied to the root zone produced promising
results. In this project we seek to test these novel approaches for improving
yields while at the same time reducing the GHG emissions associated with
agricultural production. Pakistan is the 6th largest population on the planet
and there are rarely studies or data available on agricultural greenhouse gas
emissions. Thus, the present project will investigate novel C-sequestering
fertilization strategies, but also be the founding study in Pakistan to obtain
first estimates of GHG emissions per unit of crop production or per unit of
agricultural land, under specific cropping systems and fertilizer regimes.
